CVE-2022-50195 ARM: dts: qcom: replace gcc PXO with pxo_board fixed clock

In the Linux kernel, the following vulnerability has been resolved: ARM: dts: qcom: replace gcc PXO with pxoboard fixed clock Replace gcc PXO phandle to pxoboard fixed clock declared in the dts. gcc driver doesn't provide PXOSRC as it's a fixed-clock. This cause a kernel panic if any driver...

CVE-2022-50195

The CVE-2022-50195 entry concerns the Linux kernel (ARM) where the device tree for Qualcomm clocks declared a fixed-clock pxo_board, replacing the gcc PXO phandle. The gcc driver does not provide PXO_SRC because it’s a fixed clock, which could lead to a kernel panic if a driver tries to use it. T...
